Preface

The Zend API has evolved considerably over time, as PHP has become a more
robust and widespread language. With the introduction of PHP 5 came the
Zend Engine 2 (ZE2). ZE2 came with an almost entirely new Object-Oriented
Programming (OOP) model and a number of improvements in the
API.

Aviso

This documentation is still under heavy development. The original Zend
documentation is preserved in its entirety in the
Zend Engine 1 section for those who
need it before this documentation is completed.

This section of the manual is devoted to ZE2. The differences in how
extensions are written in ZE1 are small; a short reference to them is
given in an appendix to this section.

The documentation in this section is current as of PHP 5.3.3, the most
recent stable release of PHP 5.3 at the time of this writing. Notable
differences in the minor PHP 5 releases (5.0 through 5.3) are given as
appropriate.
